Does diesel dilute with petrol (eventually)

[Nelly]

Well I have managed to put 5 litres of diesel in to my unleaded car. I had about 25 litres of the correct fuel in there already. So I thought what shall do? ↲.
↲1,Drain the tank.↲
↲ 2. Fek it fill it up and hope to dilute it down.↲So I took option 2. Is this going to screw me car or will I get away with it? Nelly

#2 is ok.
Your car will be fine. You did the right thing by diluting it down.
You might get some smoke out of the exhaust though.
Just run some fuel additive in your next tank to clean up some excess carbon that be may left behind on your spark plugs.

cheers mate, I did an internet search. It was giving me horror stories. The car is a 2001. I only need it to last until the thaw. nelly.↲ ↲
Happy new year mate.

Oops! Happens to the best of us.

Maybe check the spark plugs once the a tank or so of gas has gone through the motor to make sure they haven't fouled.

I agree with the fuel additive to help prevent funk from forming.

A friend of mine's wife did the same... except in her case it was a lot closer to 100% diesel (gas tank was nearly empty when she filled it).

We drained the diesel..... what to do? The environmental folks were having fits.... The answer was to blend it into the car's gasoline over time to burn it up. 1:12 didn't do any harm.

Thanks Pete,

Again I am a bit dim here what fuel additive do I add? Injector cleaner or an octane booster. Cheers guys.

So I should be OK on the 1:12 ratio then. The daft thing was I was showing my three year-old how to put fuel in. Then it dawned on me that I couldn't get the bloody nozzle in lol.

Don't worry he's still to young to remember.

Cheers.

Did he learn some new colourful expressions as well?

i always thought it was the other way around.. diesel engines worked ok with petrol(ive done this to the missus car)..i used to work in a haulage company where the drivers would always put a gallon of petrol in the trucks in winter ..but that was the days when diesel or the engines wernt as well refined as it these days.

hope all is Ok

it should be noted that if this was the other way around you most definitely have to drain the tank, change the filters (i do it a couple times) and try to get as much of the gasoline out. Not only will the engine barely run, the lack of lubricity destroys the pump and injectors.

they did this because diesel has much more paraffin wax and in cold weather it's the wax that causes the fuel to gel.

Just goes to show..... we, at Idiot U, are always 'raising the bar'. :cheer:

Good luck whatever happens. I did the same thing, (the trucker put diesel into the unleaded tanks!), and it took me: Draining the tank, about 8 bottles of gas additive, and month to get my car back right again! It was aggrivating, expensive, and a lot of work. (Whenever it ran out, it was like a three inch string of gasoline followed by a yellow bubble, etc, etc, etc. It never did mix or dilute!)
Sorry man.

An injector cleaner, like the Chevron Textron.

Isn't diesel oilier than gas? I'd think that instead of a lack of lubrication the problem would be an accumlation of funk. Dunno.

Good call on the filters.

urbanj is 100% correct, and your observation of diesel being oilier is also
correct, diesel injection systems are precisely manufactured with very close
tolerances, these precise parts are lubricated by the fuel passing though the
system, gasoline has about zero lubricating properties and will destroy the
system very quickly...a little diesel in a gas system will do no harm, heck the
system might even enjoy the extra lubrication...don't forget to ask my
ex-wife about diesel in the garden tractor and how it was somehow my fault

How did you fill it if the nozzle would not go in, diesel nozzles are bigger than unleaded ones?

In fairness, only had the car a week and the main family motor is a diesel.

That was not what I wanted to hear:spank:

Well M it didn't go in exactly, The filler was on the wrong side as it wasn't the car I thought I was in. I had to stretch the hose over the car, to just about get it in to the filler receptacle receiver tube device thingy..
Plus the garage I go to was updated in about 1982. All of he pumps have a certain amount of trigger pressure that makes them go or stop.It was just a bad morning after a bad few days without heating and water. This coupled with the crimbo dinner Turing out to be fish and chips.
